MathWorks Confirms Ransomware Attack: 10,000+ Users’ Data Compromised

Overview of the Breach

MathWorks, a global leader in mathematical computing and simulation software, disclosed a significant data breach in August 2025. The company confirmed that a ransomware gang infiltrated its network in April 2025, stealing the personal data of more than 10,000 individuals. While MathWorks has not publicly identified the specific ransomware group responsible, the incident underscores the escalating risks posed by cybercriminals targeting organizations with sensitive data.

What Data Was Compromised?

Although MathWorks has not released a detailed breakdown of the stolen data, breaches of this nature typically involve:

• Personal identifiable information (PII), such as names, email addresses, and contact details.
• Employee or user credentials, including usernames and hashed passwords.
• Financial or operational data, depending on the depth of the breach.

Given MathWorks’ role in engineering, academia, and research, the breach raises concerns about the potential misuse of sensitive information, including intellectual property and proprietary research.

Why This Breach Matters

1. Targeting High-Profile Organizations: Ransomware gangs increasingly focus on enterprises and institutions with valuable data, aiming to maximize their leverage for ransom payments.
2. Impact on Users: Individuals affected by the breach may face phishing attacks, identity theft, or fraud if their data is sold or leaked on the dark web.
3. Broader Cybersecurity Implications: This incident serves as a reminder of the critical importance of robust cybersecurity measures, including network monitoring, encryption, and employee training.

MathWorks’ Response

MathWorks has not publicly detailed its response strategy, but standard protocols for such breaches include:

• Notifying affected individuals and providing guidance on protective measures.
• Collaborating with cybersecurity experts to investigate the breach and prevent future incidents.
• Strengthening security infrastructure, such as implementing multi-factor authentication (MFA) and advanced threat detection systems.

How to Protect Against Ransomware Attacks

Organizations and individuals can take proactive steps to mitigate the risk of ransomware:

• Regularly update software to patch vulnerabilities.
• Use strong, unique passwords and enable multi-factor authentication (MFA).
• Educate employees about phishing scams and suspicious links.
• Backup critical data securely and test restoration processes.
• Deploy advanced threat detection tools to identify and neutralize ransomware before it encrypts data.
